Hacking Python SDK¶

  • Prerequisites
  • Get the source code
  • Run tests

Prerequisites¶

sudo apt-get install python python-pip python-dev python-virtualenv libyaml-dev

Additional prerequisites for FUSE driver:

sudo apt-get install libattr1-dev libfuse-dev pkg-config fuse
sudo adduser "$USER" fuse
sudo chmod g+rw /dev/fuse
sudo chown root:fuse /dev/fuse

After installing fuse and adding yourself to the fuse group, you need to start a new login session. Make sure the groups command reports that you're in the fuse group.

Get the source code¶

cd
git clone https://github.com/curoverse/arvados.git

Run tests¶

Strategy:

1. Install your local (possibly modified) client library to a virtualenv
2. Run the client library test suite
3. Build a client library package and install it to the virtualenv
4. Install your local (possibly modified) FUSE driver to the same virtualenv
5. Run the FUSE driver test suite
6. Build a FUSE driver package and install it to the virtualenv

Note: The test suite brings up a Keep server and an API server to run tests against. For best results:

• Try Hacking Keep and Hacking API Server to make sure you have all the right dependencies for running the Keep and API servers.
• Make sure you have a blob_signing_key in services/api/config/application.yml
